Simmonds skated in drills but did not take part in line rushes with the other forwards. Boyle was at left wing on the fourth line, where Rocco Grimaldi has played the past three games. Grimaldi didn't practice Friday, and Predators coach Peter Laviolette said he is day to day with an undisclosed injury. Grimaldi has two goals in the past three games.

Boyle and Simmonds were ruled out week to week on Monday; Boyle had an appendix procedure and Simmonds sustained a lower-body injury during a 2-1 overtime win in Game 2 on Saturday.
Whether Boyle plays in Game 5 is uncertain.
"He looked good out there today. Wayne, the same thing," Laviolette said. "When it first happened we were thinking it might be [week to week]. It's never an exact science, but they're both out there and they look good. I haven't talked to the trainer yet but we'll get a plan in here."
Boyle said he started feeling ill sometime after the Predators lost 3-2 to the Stars in Game 1 on April 10. He said he didn't know if the Predators were working him back into the lineup.
"It was just good to get out there and get off the couch," he said.
The Predators acquired Boyle in a trade with the New Jersey Devils for a second-round pick in the 2019 NHL Draft on Feb. 6. He had an assist in Game 1, and 24 points (18 goals, six assists) in 73 games with the Devils and Predators. Simmonds, who was acquireed by the Predators in a trade with the Philadelphia Flyers for forward Ryan Hartman and a conditional pick in the 2020 NHL Draft on Feb. 25, had no points in two playoff games. He had 30 points (17 goals, 13 assists) in 79 regular-season games with the Flyers and Predators.
Stars coach Jim Montgomery said forward Mattias Janmark could play in Game 5 after missing the past two games with a lower-body injury. Janmark has no points in two playoff games; he had 25 points (six goals, 19 assists) in 81 regular-season games.
